She asked me was it OK when she was so verbal and I told her it was a big turn-on. And she asked me what else I liked, and I told her that feeling her hands on my ass was sensational. She told me to lay down on my front and began massaging my ass. Nobody had hardly even touched my ass before and now it was getting a real going-over. I was quickly discovering how erotic it is to have someone touch my backside. I lifted my ass up off the bed slightly, because my cock was getting hard again. She took it as a sign I wanted more. I hadn't thought about it, but immediately discovered that I liked it when she brushed her fingertips along my crack and grazed my asshole gently. Moaned. She asked if it was OK. I admitted that it was. When she stopped moving up and down the crack and settled her fingertip against the opening of my anus..... it was electrifying.
